Psilocin,(4-HO-DMT) sometimes called psilocine or psilotsin, is a psychedelic (hallucinogenic) mushroom alkaloid. It is found in most psychedelic mushrooms together with its close congener psilocybin. Psilocin is a Schedule I drug under the Convention on Psychotropic Substances.[1] In pharmacology and toxicology, a route of administration is the path by which a drug, fluid, poison or other substance is brought into contact with the body 1. ...

Psilocin is almost identical to the chemical structure of the chemical of another known hallucinogen, bufotenin. The only difference is the position of the hydroxyl (OH-) group on the benzene ring - in psilocin, the hydroxyl group is at the 4-position in the indole ring, and in bufotenin, the hydroxyl group is at the 5-position on the indole ring. Bufotenin, also spelled bufotenine, is also known under the names 5-hydroxy-DMT (5-OH-DMT) or dimethyl-serotonin and is a tryptamine related to the neurotransmitter serotonin. ...



The Swiss chemist Albert Hofmann and the laboratory assistant Hans Tscherter from Sandoz isolated psilocin and its phosphate ester psilocybin from Psilocybe mushrooms in 1959 guided by self-administration. Dr. Dr. Albert Hofmann (born January 11, 1906) is a prominent Swiss scientist best known as the father of LSD. He was born in Baden, Switzerland, and studied chemistry at the University of Zürich. ...

Psilocin can be obtained by dephosphorylation of natural psilocybin under strongly acidic or under alkaline conditions (hydrolysis). One synthetic route uses the Speeter-Anthony tryptamine synthesis starting from 4-hydroxyindole.

Psilocin is relatively unstable in solution due to its phenolic OH group. Under alkaline conditions in the presence of oxygen it immediately forms bluish and dark black degradation products. Similar products are also formed under acidic conditions in the presence of oxygen and Fe3+ ions (Keller's reagent, FeCl3 / MeOH / HCl). Psilocin is an amine and forms salts with acids [citation needed] that are usually more stable upon storage. Psilocin base can be evaporated by heating. In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of a hydroxyl group (-OH) attached to an aromatic hydrocarbon group. ...

Psilocybin is rapidly dephosphorylated in the body to psilocin which then acts as a partial agonist at the 5-HT2A serotonin receptor in the brain where it mimics the effects of serotonin (5-HT). Psilocin is an 5-HT1A and 5-HT2A/2C agonist.
